It is a tasteless cartoon by any measure. However, nobody can deny that the current president is one of the biggest supporters of Roe v. Wade and, whether he or an opponent is in the white house next term, may have a big effect on who replaces soon-to-be retiring justices on the Supreme Court.

The the abortion thing is one of the classic examples of the liberal left forcing their agenda through the courts. Hell, even many "pro-choice" people, if they're honest, admit that Roe v. Wade was decided incorrectly and it should have been left up to the states. But the left knows that, like gay marriage for instance, they'll lose most of the time in the court of public opinion.
